(COLO) – Since the *CSP (*277) program was implemented in July 1998, Colorado motorists, bicyclists and pedestrians have reported thousands of “real-time” suspected impaired drivers. Just this year from January through July 31, the Colorado State Patrol Communication Centers have answered over 14,370 calls. 

“Every week troopers get called to investigate horrific crashes around our state from impaired drivers who are unable to navigate turns or weave in and out of their lane. These drivers destroy families as well as their own futures,” stated Chief Matthew C. Packard, Colorado State Patrol. “Driving intoxicated is literally courting disaster.”

Despite modern conveniences of rideshare companies, public transportation and the ability to contact a sober driver, impaired driving remains a top causal factor for fatal and injury crashes in Colorado investigated by Colorado State Troopers.

While there are many signs that could indicate a person is driving under the influence, some of the most notable behaviors include:

  • weaving in and out of traffic
  • swerving and straddling the lane marker or center line
  • going the wrong way in traffic
  • driving without headlights at night
  • taking wide turns
  • erratic braking
  • aggressive driving/risky driving behavior
  • impeding traffic

If you see someone nodding off behind the wheel this is another potential sign as well as an extremely dangerous situation. If you see these behaviors you are encouraged to find a safe spot to pull over and call *CSP with a description and location of the vehicle.
